Conclusion: I bought these JBL speakers and hope they will be what I wanted... I mounted them in my 18 speed boat that we run on the Hudson river in NY. I am powering them with a JL 500 watt amp and soo far great !!!
Summary: These speakers sound GREAT! They are high quality speakers and as I am going 40MPH and the wind is roaring on the boat along with my twin engines these speakers are still pumping above it all! I highly recommend these speakers to any boater!
